REFRIGERATOR.

This invention relates-to improvements in refrigerators.

The main object of this invention is to provide an improved refrigerator'or ice box especially adapted for use in groceries, ice

cream parlors and the like where it is desired to provide a refrigerating or provision chamber at low temperatures. v

A further object is to provide a structure of the class described in which the parts are readily accessible for cleaning.

Objects pertaining to details and economies of my invention'will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claim.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Fig. I is a side elevation of a refrigerator embodying the features of my invention.

Fig. II is, a' vertical longitudinal section pn a line corresponding to line 22 of Fig.

Fig. III is a transverse section on a line corresponding to line 33 of Fig. II.

partly broken away.

In the drawing similar reference numerals refer to similar parts in all of the views and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, I provide an outer box-like casing 1 open at the top and provided with a cover designated generally by the numeral 2. This outer casing has a lining or inner wall 3 of metal adapted to retain liquids.

The tank-like provision chamber or refrigerating receptacle 4 is supported on the rests or supports 5 so that the bottom of the chamber 4 is in spaced relation to the bottom of the casing and its side walls are in spaced relation to the side walls thereof providing a surrounding refrigerant chamber 6. The provision chamber or receptacle 4 is tapered downwardly so that the vertical por- Fig. IV is a plan view with the cover,

tions of the refrigerating chamber are tapered upwardly. This prevents the refrigerant from choking and clogging and enables its being readily packed in the refrigerating chamber, cracked ice or ground ice with a suitable chemical being preferably employed as a refrigerant.

The cover 2 serves as a cover for the provision chamber 4 as shown in Figs. II and III. The cover has. elongated openings 7 above the vertical portions of the refrigerating chamber, these openings being normally closed by the closure members 8 carried by the cover. This facilitates the introducing of the'refrigerant and packing it in the refrigerant chamber.

The cover is also provided with a series of openings 9 above the provision or refrigerating chamber, these openings being normally closed by the lids or closures 10 so that, if desired, cans such as ice cream cans may be placed in the refrigerating chamber and are accessible through the openingsS, or the articles may be introduced and removed through these openings without removing the entire cover 2. The cover 2 may, however, be removed when it is desired to remove the chamber 4. for cleaning.

A waste pipe 11 is provided for drawing off surplus liquid from the refrigerating chamber. This is preferably controlled by a valve 12, the outlet of the pipe being above the bottom of the refrigerating chamber determines the normal level of the liquid when the valve is left open.

My improved refrigerator is very efficient and is adapted for the maintaining of relatively low temperatures. I have illustrated and described an embodiment which I have found very practical. I havenot attempted to illustrate or describe certain modifications and adaptations which I contemplate as I believe the disclosure made will enable'those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: r

In a refrigerator, the combination with box-like casing, a tank-like provision chamher supported within said casing with the bottom of the provision chamber in spaced relation to the bottom of the casing and its side walls in spaced relation to the side walls 5 of said casing providing a refrigerant 'chamber surrounding said provision cham ber, the side walls of said provision chamber being converged downwardly so that the Vertical portions of the refrigerant chamber are tapered upwardly, and independent closures for said provision and refrigerant chambers.

In witness whereof, I have hereunto set my hand.

WILLIAM P. WILLSO'N.
